In the Natural Gas refining process, Molecular Sieve is used to remove unfriendly elements like water, hydrogen sulfide, organic sulfur (thiols), carbon dioxide, and other impurities create a natural gas that is ultra purified.



The presence of moisture will notably make the dew point rise. Ice inevitably forms in liquefied gas, pipeline transportation, or cryogenic separation and may also form hydrocarbon hydrates that precipitate and block devices and pipes.  The moisture is especially troublesome when it reacts with H2S, CO2, etc. in natural gas, causing corroded devices and pipes.  Using Molecular Sieve for natural gas processing is a simple, effective, and cheap way to dehydrate your stream.


H2S, CO2, etc. can react with the water that is present in the natural gas, which will cause pipeline and equipment corrosion; natural gas containing high levels of H2S and CO2 should be purified by Molecular Sieve before use.
